W1 T NESSES IVILLIAM F. SMITH, OF WHITEOROSS, COLORADO.

ORE-SLIIVIER.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed April 4, 1905. Serial No. 253,824.

To all whom, it may concern:

Be it known that I, WVILLIAMF. SMITH, a citizen of the United States, residing at IVhitecross, in the county of Hinsdale and State of Colorado, have invented certain new and useful Improvements in Ore-Slimers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in ore-slimers, and is particularly adapted for saving the values found in the tailings from ore-mills.

It is the object of the invention to take such tailings and manipulate them so that the heavier substances can be removed therefrom, and the slimes can be further treated for filtering and removing any lighter values which they may contain.

lVith these objects in view my invention comprises certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal central vertical section through the movable floor and the casing carr in the same which first receives and o erates upon the tailings taken from metallic ores. F ig. 2 is a side elevation of the same. Fig. 3 is a perspective view, partly broken away, of a tailing and slime treating mechan ism made up of a plurality of units. Fig. 4 is a perspective view, of an intermediate filtering member for treating the slimes. Fig. 5 is a transverse vertical sectional view through the same. Fig. 6 is a detail perspective view of the slime treating and filtering box. Fig. 7 is a vertical transverse sectional view through the same.

The tailings from ore-mills or other mechanism which has been employed for treating ores often contain considerable values in metals or other substances which are generally lost for lack of further separating and treating mechanism.

The: present invention is designed for so acting upon and treating the tailings and slimes of ore metals as to separate and extract such values as may still remain in the tailings.

I have illustrated in the drawings connected members which cooperate in treating the tailings and slimes, and the relative and usual cooperative arrangement of the parts is clearly shown in Fig. 3, in which will be found the tailing-receiving floor or casingA, and an intermediate filtering slime-treating tank B, together with a further slimetreating box and filtering device 0. The other views in the drawings set forth upon a larger scale the details of construction of these various casings. The tailings are first received by the casing or floor A, which is provided with sides l of any suitable height for retaining a suitable amount of material and the said casing is movably mounted, so that the materials placed therein may be shaken or agitated over the bottom thereof. To effect this purpose, the said casing rests upon wheels or rollers 2, which operate upon a guiding and supporting base 3. The move ment of the casing is had between side guiding ledges or strips 1*, which strips also limit the endwise movement of the rollers The base 3 is formed with depressed bearingsurfaces 2*, upon which the rollers 2 move.

The reciprocating movement of the casing and floor A is produced in any desired manner, a simple means being shown in the drawings and comprising a crank 5, which is journaled in the base 3 and is connected by means of a pitman 4 with the casing A, as clearly shown in Figs. 1 and 3. A rotation of the crank 5 by any suitable means will accomplish a reciprocating movement of the casing upon the rollers 2. The bottom of the casing A is provided with irregular surfaces 6, which extend upwardly from said floor, and are preferably stepped, as illustrated in Fig. 1, recesses being formed between the irregular projections for receiving and holding the heavier values found in the tailings. The casingA is provided in one end with an outlet-opening 7, controlled by a slide 8, and a trough 9 carries off materials which pass through the said opening 7.

In operating the device the outlet 7 is opened from time to time for allowing sand and other waste matter to escape from the casing A. The slime fills the casing A and carries the lighter values out from the upper part thereof, finding a passage from the casing through a trough 10. The casing is also provided with doors in the sides thereof, as at 11, through which the values collected may be removed. The trough 10 extends at its outer discharging end over one of the intermediate treating boxes or tanks B. This intermediate box or tank B is so constructed as to collect and hold lighter values which may still remain in the slime by the process of filtration. For this purpose the tank B is provided with inclined screens 15, the said screens being covered with jute or other liltering material to accomplish the catching of the lighter values. The slime is deposited upon the bottom. 12 of the tank B, falling between the iilters or screens 1.5, and in order to escape from the said tank B, the slimes must rise in the box and pass through the screens 15 to reach outlet-passages 141, formed in. the side walls of the said tank, The greater portion of the lighter values which remain in the slimes will thus be filtered from the water and collected within the box B by means of the filter-screens 15. The water free from the values collected by the screens 15 will be allowed to pass from the doors 14 into a discharge-trough 1st, arranged upon the sides and ends of the tank 15. The tank B is also provided with an overflow outlet or trough 13, through which the slimes pass and are permitted to fall in the adjacent slime box or tank C. The tank or box C is formed with walls 17 of suitable height, and. a filteringscreen 18 is arranged therein within which the materials passing through the trough 13 drop. In this tank the lilters 18, which are also made of screens with jute or other materials applied thereto, are arranged about the sides and one end of the box. and preferably incline inwardly, as clearly seen in Figs. 6 and 7. Any remaining values in the slimes will be caught and retained. by the filteringscreens 18, and the water may be permitted to pass 011 through a discharge-outlet 19, controlled by a suitable door or slide, a trough 20 conducting the water passing through said, outlet 19 to any suitable point. The tank C is also provided with a door 21 in one of its walls through which the remaining slime is removed. The tank B also provided with a door 22 in one of its walls, through which any settlings of value in said tank may be removed.

The operation of the mechanism will be evident from the above description, and the treatment of the tailings and slimes as set forth is found to remove and save all the values which were contained in the tailings. It will be evident that a plurality of tanks C may be used if desired without departing from. the spirit of the invention. The materials collected upon the screens 15 and 18 may of course be removed at any suitable time. It is preferable to contract the upper edges 01 the screens, as shown in Figs. 5 and 7, for insuring the proper collection. of the remaining values of slimes.

Referring again to the screens 15, although they may be permanently secured in. the tank B, they are prel erably removably arranged therein, resting upon inclined cleats 1.5 at the ends of the tank and being held or locked. in position by wedges 16, which are placed in the ends of the tank between the screen and. the side thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an ore-slimer, the combination with a receptacle for dispensing ore tailings, of a series of slimes-filters made up of intermediate boxes having outlet-openings in their walls, removable screens mounted within said walls, means for binding the screens in place and an end. tilteringbox having liquid-out lets in its walls and side and end. inclined screens converging upwardly and arranged to intercept the liquids as they pass out of said end. box.

2. An ore-slimer, comprising a slime-receiving filtering-tank, having upward ly-converging filtering-screens mounted therein, and a final filtering-tank having inclined, upwardly-converghlg filtering-screens arranged at the sides and one end, and having an overflow and controlling slide adjacent to the end. screen, and an opening and door in the opposite end, tor removing settlings of value.

3. An ore-slimer comprising one tank having inclined filtering-screens connected to opposite ends of the tank, and with a valuedischarge door at one end and an overflowspout at the opposite end, and both disposed between. the screens, and another tank arranged to receive overflow from the spout and having inclined screens connected at one end and inclined from the opposite end and with a value-discharge door between the screens and a refuse-discharge door in the end opposite.

In testimony whereof I afliX my signature in presence of two witnesses.
